Y/JTG-1下架式陀螺全站仪快速定向

快速精确定向是现代陀螺定向测量的重要研究方向。本文利用下架式陀螺全站仪跟踪测量法精确测定了仪器分划板格值τ和悬带零位系数λ两个重要参数,从而使悬带零位改正更加可靠。并基于下架式陀螺全站仪跟踪测量法进一步提出采用连续采样跟踪法实现快速定向。利用跟踪一个周期的数据进行定向测量,耗时仅需12min左右,定向精度与积分法相当。

On the fast orientation method for Y/JTG-1 Gyro-theodolite

Fast and accurate orientation is a major studying direction in gyrostatic orientation survey now. In this paper, the Track-of-reversal-points method is used for the gyro-theodolite and two important parameters τ(reticle scale ) and λ(the coefficient of tape zero) are determined. As a result, the correction of tape zero is more reliable. Based on this method, a technique of continuous sampling is put forward to realize orientation quickly with Y/JTG-1 gyro-theodolite. By using one periodic data, the time of orientation can be shortened to 12 minutes or so and the precision of orientation is equivalent to integral surveying method.
